Specification forming part of Letters Patent No. 4S,059, dated June 5,l.

.To all whom it may concern:

Be it known that l, l?. S. Haines, of Newburg, in the county of Orangeand State of New York, have invented a new and useful Improvement inGarding-Machines; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference beingv had to theaccompanying drawings, forming part of this speciiication, in whichiFigure l is a rear elevation of a carding-machine to which my inventionis applied. Fig. 2 is a` vertical cross-section taken on line x of Fig.J. Fig. 3 is a side view of the same parts seen in Fig. l.

Similar letters of reference indicate corresponding parts.

This invention consists, among other things, in a new mode of operatingthe doffer-comb of a carding-machine, by which it is reoiprocated in anearly-vertical direction, and caused to strip the doffer-cylinder in amore perfect manner than has hitherto been effected.

K designates the frame, A the main cylinder, and B the doffer-cylinder,of a cardingmachine. i

C designates the taker-off 7 or doffer-comb, which strips the materialwhich is being carded off. from the doffer-cylinder B. rlhe said combconsists of a plate with a straight or serrated edge,as desired,placedvertically behind the dofer-cylinder, its ends being carried be,

youd the ends of the cylinder in order that they may be attached to theouter ends of springs or spring-plates M, which project from anyconvenient part ofthe frame. The springplates M here shown projecthorizontally above the journals of the (leder-cylinder. Thedoffer-combis carried by rods or plates J, to whose upper ends it is attached, adjustably, by means of set-screws which pass through vertical slots in thesaid plates J. The lower ends of said plates terminate in straps whichencircle eccentrics I, fixed on anshaft, H, running in hanging bearingsN, which depend from the rear ends or rails of the frame K. llhesehanging bearings are adjustable to different heights, so as to elevateor depress the shaft H, as desired, and their shanks are clamped at anydetermined position by means of nutsO, which hold them to the rails ofthe frame. rlhe righthand end of the shaft H, Fig. l, has a pulley, G,which is driven by a band from a pulley, U, on the outside of the frame,and which pulley U is fixed on a short shaft, D, that extends only alittle distance each way from that side ofthe frame K in which it runs.It carries, also, another pulley on the inside of the frame, as seen indotted outline in Fig. 1, around which runs a band, E, (indicated in redoutline, from the stripper-shaft.

By this device I dispense with the usual waste-shaft, 7 which extendsbeneath the mai n cylinder, running in bea-rings in the sides of theframe, and effect the same object for which th at shaft was employed-towit, operating the doffer-comb by means of the short shaft D, whichextends only far enougheach side of that part of the frame in which itruns to enable it to carry the pulley U outside of the frame,

and the pulley seen in dotted outline on the inside thereof.

My object in doing away with the Wasteshaft is, iirst, to enlarge thespace below the main cylinder, so that the operativescan have betteraccess to that part of the machine and with less danger to themselves;second, to save that part of the material which is being carded thatusually clings to said shaft, and, thirdly, to cheapen and simplify theconstruction of the machine. f

In order to make the shaft H run with steadiness,l`have placed thereontwo eccentric hubs, P l?, each of which has a collar, V, which is fixedto the shaft, and a set-screw. rEhe hubs are so placed on the shaft thattheir longer radii shall be on the opposite side to the longer radii ofthe eccentrics I, thereby balancing the shaft. The direction of motionof the shaft H is to be such that when the doffer-comb rises it iscarried away from the doffer B, because the greatest throw of theeccentrics is then outward. Vhen the plate is carried downward, theirgreatest throw is inward toward the doffer-cylinder, thereby causing thecomb to approach lthe same during that part of its movements.

Since the ends of the comb-plate are fixed to the ends of thespring-plates M, it is evident that the comb in its up and downmovements describes an arc of which the spring plates or arms M areradii.
